Description
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a National Stage of International Application
No. PCT/EP03/06010, filed on Jun. 7, 2003, which claims priority to
German Patent Application No. 102 30 492.0, filed on Jul. 6, 2002.
The disclosures of the above applications are incorporated herein
by reference.
BACKGROUND OF THE INVENTION
The invention relates to a device for fixing a housing, especially
the housing pertaining to a motor-vehicle battery, to a carrier
plate.
Housings of motor-vehicle batteries have an essentially cubic
shape. Typically, they rest on a carrier plate, one end of which is
bent elastically and engages a side wall behind a step. The
opposite side wall likewise has a step, and on this side the
carrier plate projects past the housing base. For fixing the
housing to the carrier plate, one end of a leaf spring bent into an
S shape is brought into contact as an attachment flange with this
step, while the other end rests on the projecting carrier plate. A
screw passing through the flat middle part of the leaf spring and
through the projecting part of the carrier plate is secured with a
locknut. This type of attachment is complicated: it requires a
series of manipulations and can be fixed and loosened again, if,
e.g., the battery is to be replaced, only with the aid of a tool.
Therefore, it requires a considerable amount of time. Recycling the
flange and screws according to European guidelines presents another
problem.
SUMMARY OF THE INVENTION
The problem to be solved by this invention is to create a device
for fixing a housing, especially the housing pertaining to a
motor-vehicle battery, to a carrier plate, where this device allows
the housing to be fixed to the carrier with a few simple
manipulations and without the use of a tool, so that it can also be
loosened again quickly if need be with the use of a simple tool, if
necessary. For repeated replacement of the housing or the battery,
there should be no accumulation of scrap parts.
According to the invention, this problem is solved by a device,
which comprises a fixing bracket and a separate fixing element,
where the fixing bracket is fixed or molded onto an edge of the
carrier plate projecting past the housing and a vertical limb that
extends at a distance from the housing wall and is parallel
thereto, and where the separate fixing element can be inserted into
the intermediate region between the housing wall and the vertical
limb of the fixing bracket and wedged securely therein. This can be
performed quickly with minimal expenditure of force and without the
aid of a tool. All of the parts of the fixing device can be reused
when the housing is replaced, so that no scrap or waste parts are
created.
For wedging the fixing element, preferably a contact surface for
one end of the fixing element is provided on the wall of the
housing and engagement means for the other end of the fixing
element are provided on the vertical limb of the fixing
bracket.
The contact surface on the housing wall for the one end of the
fixing element can be formed by a step projecting laterally near
the base; for the engagement of the other end of the fixing
element, an undercut can be provided on the inside of the vertical
limb of the fixing bracket. To make the engagement more secure, a
catch can also be formed in the undercut.
The separate fixing element preferably consists of top and bottom
parts, which are interconnected by a hinge, thereby permitting a
folding motion between the two parts. This folding motion of the
two parts allows the fixing element to be wedged between the
housing wall and the fixing bracket.
According to a preferred embodiment of the invention, the two parts
have an essentially rectangular outline, and their side surfaces
opposite the hinge form an angle, which permits the folding motion
between the two parts.
Preferably, a perpendicular rib for engagement with the undercut in
the vertical limb of the fixing bracket is provided on the end
surface on the free end of the top part. This rib can also be
formed on the end surface of a cap formed on the top part.
In the top part, there is advantageously an opening, which can be
engaged with a simple tool, e.g., a screwdriver, in order to
release the wedging of the fixing element between the housing wall
and fixing bracket again when necessary.
The intended wedging effect is improved when the bottom part
increases in height from the hinge outward toward its free end; the
end surface on the free end is then sloped steeply and on this end
surface a support surface is formed, which can contact the side
wall of the housing, preferably at the contact surface formed there
by a step. The surface of the part rising from the hinge outward
can contact a support edge formed in the inside of the vertical
limb of the fixing bracket, so that the bottom part is supported at
two or more points, while the top part is brought into engagement
on the vertical limb of the fixing bracket, which produces a secure
clamping effect.
According to an embodiment of the invention, the top part consists
of a thin-walled, flat base and thin-walled side walls, and the
bottom part consists of a thin-walled base rising from the hinge
outward and thin-walled side walls. The hinged connection is then
realized at the edges of the side walls of the narrow sides of the
opposing parts.
Laterally extending projections can be provided on the bottom part.
The end surfaces of these projections are aligned with the support
surface on the free end of the part, which increases the overall
support surface of the bottom part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1 shows schematically a part of the housing 1 of a
motor-vehicle battery, which has, in a known way, a step 2, which
is formed preferably with a slight slope, laterally across the base
of the housing. The housing 1 rests on a carrier plate 3, which on
this side projects past the housing 1. On this side of the carrier
plate 3, there is a fixing bracket 4, which can be integrally
molded with the carrier plate 3 or connected rigidly thereto in
some other way. Extending from the fixing bracket 4, which is shown
again separately in FIGS. 8-10, is a long vertical limb 5 parallel
and at a distance to the side wall of the housing 1. A
reinforcement rib 6 is preferably provided on its outer side. First
of all, a shorter horizontal limb 7 is used for fixing plate 3 to
the carrier and forms a right angle with the vertical limb 5 at
least on the inside of the fixing bracket 4, so that here a
horizontal contact surface 8 is produced for a separate fixing
element 9, which, as described below with reference to FIGS. 1-3,
is to be inserted and wedged between the side wall of the housing 1
and the inner surface of the vertical limb 5 of the fixing bracket
4. Side walls 10 on the vertical limb 5 of the fixing bracket 4 are
used, on the one hand, for reinforcing the bracket 4 and, on the
other hand, for securing the fixing element 9. An undercut 11 on
the free end of the vertical limb 5, which has on its front edge a
small catch 12, is used for wedging the fixing element 9 in the
fixing bracket 4 (see below). In addition, in the angled region of
the fixing bracket 4 on the inner side of the vertical limb 5,
there is a step which provides a support edge 13 for the fixing
element 9.
FIGS. 4-7 show a preferred embodiment of the fixing element 9. It
consists of two parts 14, 15, which are rectangular in their
outline and which are connected to each other by a hinge 16. In the
illustrated embodiment, the top part 14 consists of a relatively
thin-walled base 17 and reinforcing side walls 18, which give it
the shape of a flat box. In the base 17 there is a slot-shaped
opening 19 as possible engagement for a simple tool, e.g., a
screwdriver. On the one free narrow side of the top part 14, there
is a projection 20 extending over the entire width outside on the
base 17 with a trapezoidal cross section, whose surface aligned
with the narrow side wall of the part 14 is provided with a
perpendicular rib 21. The hinged connection 16 with the bottom part
15 is realized at the edge of the opposite narrow side. The side
walls of the two parts 14, 15 opposite each other are inclined
outward from the hinge 16 slightly away from each other; thus they
form an angle that permits hinged motion between the two parts 14,
15.
The second, bottom part 15 also consists of a thin-walled base 23
with reinforcing side walls 24, but the base 23 rises from the wall
of the narrow side lying opposite the top part 14, so that the
bottom part 15 increases in height toward its free end up to a
flattened strip 25, from which, outwardly, a steeply inclined, free
narrow side 26 is formed, which transitions into a vertical support
surface 27. Blade-like projections 28 can be formed laterally on
the part 15. These blades are used for reinforcing the part 15 and
also for increasing the support surface 27.
The fixing of the housing 1 on the carrier plate 3 is realized
according to FIGS. 1-3 in the following way:
The housing 1 is set on the carrier plate 3 and, e.g., as before,
pushed with the edge (not shown in the drawing) formed on its one
side wall just over its base under the surrounding elastic edge of
the one side edge of the carrier plate 3, so that fixing is already
achieved here. The vertical limb 5 of the fixing bracket 4 is then
parallel and at a distance from the opposite side wall of the
housing 1. The fixing element 9 is now inserted with the bottom
part 15 increasing in height toward its free end into the
intermediate region between the side wall of the housing 1 and the
vertical limb 5 of the fixing bracket 4 (see FIG. 1). With the edge
of its support surface 27 formed on its free end, it comes into
contact on the step 2 located on the side wall of the housing 1.
Due to the hinged connection 16 between the bottom part 15 and the
top part 14 of the fixing element 9, a folding motion of the top
part 14 reduces the angle between the opposing side surfaces of the
parts 14, 15 so that the rib 21 on the free end of the top part 14
can be brought into engagement with the catch 12 in the undercut 11
of the fixing bracket 4 (see FIG. 2). In the region of the hinge
16, a force directed opposite the previous folding motion is
exerted on the fixing element 9; its top part 14 is set with its
base 17 again parallel to the vertical limb 5 of the fixing bracket
4; and for its part, the bottom part 15 performs a folding motion
in the hinge 16, increasing the angle between the two opposing side
surfaces of the parts 14, 15, whereby it slides with its support
surface 27 formed on the free end completely on the inclined step 2
on the side wall of the housing 1 and is finally supported with its
diagonal base 23 on the support edge 13 formed by a step on the
inside of the vertical limb 5. In this folding motion, a point is
reached at which the fixing element 9 can no longer automatically
spring back from this position. This produces a permanent clamping
effect that holds the housing 1 securely to the carrier plate
3.
This process can be practically realized without the aid of any
tool. To loosen the housing 1 from the holder, a simple tool, e.g.,
a screwdriver, can be inserted into the opening 19 provided in the
base 17 of the part 14, and the fixing element 9 can be released
from its wedged position.
